comment A Star pathfinding algorithm, multiple node set optimization
even if you use all those coordinates as A* nodes there won't be a noticeable performance cost... 135*185 < 150*200 = 30000 ~ 0.002s computation time. Compare that to 0.0167s that you have to render each frame. Also note that Usually it won't even take 0.1ms, I've computed the worst case time.

comment OpenGL Textures have distorted colors on some android devices
I'm not sure, but you might be using some kind of pixel representation that is not supported on those devices.

comment cocos2d-x “immediate mode”?
a) if you are going to use v3.x you should use custom command, either with draw or visit. and personally I prefer draw method since it almost needs no boilerplate code to make compatible with other stuff. b) porting to other systems is the biggest advantage. Also there are lots of other stuff that might help you in way (like textures, audio, debug helpers, ...) but you might take a look at SDL2 too (that's what I've migrated to for just one of my projects which required to run without GUI in some cases). c) As far as I know, there is absolutely no advantage of using scene graph in your case.

it would have been nice, if you threw a link to frame-buffer too.

comment Is this possible in cocos2dx 3.0?
@Dhruv-user3531484 you can always google stuff, and you can use the engine documentation. I mean you should have gotten a compile error for that code...

comment Estimated framerate for custom engine?
does it really matter? I mean as long as you are above 60fps, continue development, and as soon as you got under it, start optimizing.
